Oc4j to Weblogic: JAAS login module in enterprise web application

Hi Experts,
I have a LoginModule defined in my existing EAR application.
oc4j doc referece: http://download.oracle.com/docs/cd/B31017_01/web.1013/b28957/loginmod.htm#BABECDDC
I already followed Developing Custom Security Provider : http://download.oracle.com/docs/cd/E12890_01/ales/docs32/dvspisec/progrmng.html
How can I integrate LoginModule same way in weblogic..(10.3.4) thank you all in advance. Already know the process of MBean jar and configuring it in weblogic console.
But Standalong MBean JAR can't find my Custom LoginModule defined in EAR which I am pointing from my CustomSecurityProvider thru
getLoginModuleConfiguration()Thanks for reading my post.. hoping to get some response..

is this even possible, is it a bug? anybody from weblogic team??

JAAS Login Module using Deployable Web Service proxy

Hi,
We've created a JAAS Login Module that calls a deployable web service proxy to validate users on Netweaver Portal 2004 SP19. To do this the following steps were taken:
1) created a deployable web proxy named 'SGU_proxy' and uploaded it to server. This project created 2 files: 'SGU_proxy.ear' (the one uploaded) and 'SGU_proxyClientAPI.jar'.
2) created a Java project named 'AgregacaoLoginModule' with a single class to authenticate users, this is the class that calls the web service with the username and password. This project references the deployable web proxy project (Properties > Java Build Path > Projects > checkbox marked next to project SGU_proxy).
3) exported the Java project class, not including the 'SGU_proxyClientAPI.jar'.
4) created a 'J2EE Server Component' > 'Library' project named 'AgregacaoLoginModuleJ2EE'.
On the 'provider.xml' file added 2 jars: 'AgregacaoLoginModule.jar' and 'SGU_proxyClientAPI.jar'. References were made to the standard portal libraries. No references were made to the proxy 'SGU_proxy' or the 'AgregacaoLoginModule' project.
The library was uploaded to the server, everything was ok and no errors were reported.
The login module was configured on the server and is called when users try to acess Portal server.
The problem is that when trying to authenticate users: after getting a reference to the proxy using jndi I get a ClassCastException. Note that this proxy is used in a WebDyn Pro application and is working fine.
The web service client proxy generated the interface 'pt.agregacao.ws.sgu.Servicos' and from jndi I get 'class pt.agregacao.ws.sgu.ServicosImpl'. So this seems to be ok, why the exception?
Is it necessary to had a reference to 'SGU_proxy' on the 'AgregacaoLoginModuleJ2EE' project? If so, how?
Thanks in advance.

Custom JAAS login module configuration in Oracle application server

I have a LDAP login module implementing javax.security.auth.spi.LoginModule. This login module works well with tomcat and weblogic, if I configure the JVM arguments -Djava.security.auth.login.config and -Djava.security.policy to point to the login.conf and access.policy files. The login.conf file has the below content
FREEWAY_SERV
com.wipro.freeway.security.LdapLoginModule required debug=true portal=false;
FREEWAY_PORT
com.wipro.freeway.security.LdapLoginModule required debug=true portal=true;
The access.policy file has contains content like below:
grant Principal com.wipro.freeway.security.RolePrincipal "UserAdministration" {
permission com.wipro.freeway.security.URLPermission "/createOtherUser.frw";
permission com.wipro.freeway.security.URLPermission "/createDealer.frw";
The application uses these login modules by passing Name of the JAAS configuration (FREEWAY_SERV or FREEWAY_PORT).
I would like to use the same login module and code in Oracle application sever 10.1.3 and I haven't got any success yet. I am not getting how to set these JVM properties and make my application identify this custom login module. I have tried configuring the custom login module via oc4j admin console and I couldn't give a name to my configuration. I also set the system properties for
-Djava.security.auth.login.config and -Djava.security.policy with no success.
Could anybody please help me to get this right?
Thanks in advance.

Hello,
In OracleAS 10g R3 (10.1.3.x) you can register your login module in your application (and server) using Enterprise Manager, and config file. That is easier and more flexible that the parameter.
I would invite you to take a look to the security how-to:
- 10.1.3 How-tos, and How to integrate a custom login module
You can also take a look to the 10.1.3 Documentation and the LDAP/Login Module integration.
- Security guide: Login Modules

Hi,
in OracleAs bet is to use Enterprise Manager to configure the login module. The LoginModule needs to be configured in the system-jazn-data.xml file, which is located in teh j2ee/home/config directory of the OC4J you use. Enterprise Manager does this all for you.
In your application deployment the orion-application.xml file needs to specify that a custom LoginModule should be used. Again ENterprise Manager does it for you.
To use the LoginModule e.d. for J2EE authentication, just make sure that the application name of the J2EE deployment matches the name of the LoginModule configuration
If you want to use pure JAAS you may have to change the OC4J properties file in the j2ee/home/config directory. Best suggestion to give is to get the online documentation for OC4J security

Is it possible to define new JAAS module that would first check with Oracle DB & then check with LDAP directory. Actually my requirement was to authenticate user with the help of backends. Here backend denotes both Oracle DB & LDAP. In the sense when user enters valid id & password it checks for existence in DB & if exist DB returns a new value (role) then have to check new value with LDAP( what are the privileges available for specified role & who is the superior for the same). The details maintaining in LDAP are dynamic so we cant able to move into DB. Every process involving here is automatic in the sense no external server connection should provide for authentication. The custom login module should be deploy in same OC4J container. Always available as service. I want to know about the following
1) How to define costom JAAS login module
2) How to configure coutom JAAS login module over OC4J
3) How to make use of it
Thanks,
Rajesh

How to deploy and configure custom JAAS login module

Dear Experts,
I have created a custom jaas login module, In my .jar I am having
1. MyLoginModule.class
2. Handler.class
3. MyPrincipal.class
I want to know how to deploy the custom jaas module to oc4j. And make available to all
other application to use the same for authentication & authorization. Please suggest me.
Thanks,

This article does not mention that you can put the <jazn-loginconfig> tag into the orion-application.xml as well.
Much easier to deploy and test.

JDEV deployment of web app with custom JAAS login module fails

For the first time, I am trying to implement a custom JAAS login module.
JDEV deployment to standalone OC4J only fails when my orion-application.xml is included. The deployment fails with a java.lang.InstantiationException.
This what I have done:
1) Wrote a custom LoginModule called com.whirlpoool.sjtc.jaas.gpa.LDAPLoginModule.
2) Put it and its dependent classes in a jar named sjtcjaas.jar.
3) Put the jar in $ORACLE_HOME\j2ee\home\lib
4) Changed library_path in $ORACLE_HOME\j2ee\home\config\application.xml to
<library path="../../home/lib/scheduler.jar;../../home/lib/sjtcjaas.jar" />
5) Added an orion-application.xml to the JDEV project. (I used an Oracle How-to as a pattern, see below.)
I think I'm close but no cigar, yet. Any help would be appreciated.

Custom JAAS Login Module 9.0.4 configuration problems

Hello,
We have created a custom JAAS Login Module on OC4J 9.0.4 and are having some sort of configuration problem
We always get this error:
Caused by: javax.security.auth.login.LoginException: Login Failure: all modules ignored
     at javax.security.auth.login.LoginContext.invoke(LoginContext.java:779)

     at javax.security.auth.login.LoginContext.invokeModule(LoginContext.java:607)
     at javax.security.auth.login.LoginContext.login(LoginContext.java:535)
The Login Module is configured for a specific deployed application in the global jazn-data.xml and is being run as I have attached a debugger to the app server.
Our authentication process succeeds and we return a "true" from the login() method. No exceptions are thrown from our Login Module.
our ORACLE_HOME/j2ee/home/config/jazn-data.xml has this added

The j2ee/home/application-deployments/helloworld/jazn-data.xml looks like this:
<?xml version="1.0" encoding="UTF-8" standalone='yes'?>
<!DOCTYPE jazn-data PUBLIC "JAZN-XML Data" "http://xmlns.oracle.com/ias/dtds/jazn-data.dtd">

and we added this into the j2ee/home/application-deployments/helloworld/orion-applicaton.xml
<jazn provider="XML" location="jazn-data.xml" >
<property name="role.mapping.dynamic" value="true"/>
<property name="custom.loginmodule.provider" value="true"/>
<property name="jaas.username.simple" value="true" />
</jazn>
Are we missing anything? Our code runs, it seems like there is something lacking in the configuration on the OC4J side of things.
Anyone know what we are missing?
Thanks....

Hi,
if you are on 9.0.4 then <property name="custom.loginmodule.provider" value="true"/> shouldn't work because its a parameter of 10.1.3

Urgent: JAAS Login Module Deployment Problem

Hi,
I have developed a JAAS Login module for the portal (EP6 SP9 sneak preview) and i am getting the following error:
GroupAssignmentLoginModuleLibrary does not exist in LoadContextWrapper.modifyName.
com.sap.engine.services.security.exceptions.BaseSecurityException: Can not load a login Module
The next line is a ClassNotFoundException for the Login Module and the class found in negative cache.
Please let me know if you know the solution to this problem.
It is an urgent issue and a solution will be suitably rewarded.

Hi Diego,
Scenario 1: SAP EP to SAP Backend Integration
      In this scenario the most commonly used strategy
      is SAP logon tickets. As far as I know this is the
      best and simple way to implement SSO.
Scenario 2: SAP EP to Non SAP systems.
      In this scenario various mechanisms can be used.
      It depends on the application you are integrating
      with. SAP does deliver SSO soultions with Lotus
      Notes and Outlook etc. If supported probably it is
      simple to use the SAP solution [Reliability and
      Support].
Scenario 3: Enterprise Uses third party authetication
      Software.
      For the authntication if the company chooses to use
      some third party product like SiteMinder etc, then
      you can simply use this solution for SAP EP authe-
      tication, and also all your other enterprise
      applications based on the product support. But SAP
      EP to other SAP systems be best integrated with SAP
      logon tickets.
Scenario 4: SSO using homegrown authetication or some
      third party JAAS module.
      If you have significant applications that are home
      grown that uses some custom authentication mecha-
      nism (Example: Authentication based on ID and
      Password stored in company database ) you can write
      a JAAS module extention to authenticate using that
      database. In other words JAAS is flexible and
      for using external authentication mechanisms.
There are several mechanisms available that all depends
on your internal applications/security mechanism/integration etc.
Here is the link to one of the good articles on SDN about the SAP supported SSO mechanisms.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/58094632-0301-0010-a391-fc0de26f010e
Hope this information is useful.

Retrieving JDBC connection from datasource in JAAS login module

Hi,
I have a custom JAAS login module which calls a DAO for accessing user login details. The DAO looks up the datasource to retrieve connections from when the LoginModule is initialized.

It seems the datasource is valid but trying to retrieve connections from it will fail.
Anyone had any similar problems??

Nope, sorry ... I am also having other troubles with JNDI lookups, this time from within the init method of a filter ... Seems there may still be some issues here for Sun to iron out ...

"HttpServletRequest" from ContextHandler in JAAS Login Module

Hi All. I've developed a custom authenticator in WL 9.1. This CA has a custom JAAS Login Module. Inside this module I use weblogic.security.auth.callback.ContextHandlerCallback in order to get javax.http.servlet.HttpServletRequest using the key HttpServletRequest.
This component works properly in WL 9.1 but using the same component with the same configuration in WL 9.2 I'm experiencing a null pointer getting HttpServletRequest from context handler.
Any idea about this issue ?
Regards.

i am new to JAAS. I am trying to write a custom authenticator in weblogic 9.2. how did u get the handle to ContextHandler to get the httpservletrequest.

Opinions on implementing a JAAS login module to achieve SSO

We are looking at implementing SSO from a sharepoint website to the portal. The users who are accessing the Sharepoint site are using their own computers and are not members of the AD Domain, so they could theoretically be using any computer in the world to access Sharepoint.
the desired user experience looks something like this.
user--login> sharepoint site -no login--
>portal
One of the methods we are looking at to achieve this is to implement a custom JAAS login module that would authenticate the user if they are coming from the Sharepoint site.
I would like to get your opinions on how viable you think this method is. One of the goals of this method is ease of implementation, so if you can think of an easier way to implement this please let us know.
the method is basically this.
1. User logs into sharepoint using their AD username and password and establish an active session with sharepoint
2. user navigates to a link in sharepoint that points to a resource in the SAP Portal
3. we don't want the user to have to login to access the resource when they click on the link
4. to facilitate this, sharepoint has constructed the link in the following way
5. the link is an https link
6. the link has two additional parameters in addition to whatever is necessary to navigate to the resource
7. the parameters are
8. un = the users AD username
9. uh = sha1("secret_password_known_to_both_the_login_module_and_sharepoint" + "username")
10. the user clicks the link and is directed to the SAP portal
11. the sap portal has a custom JAAS login module which performs it's checks before the other login modules
12. the custom module computes ( sha1("secret_password_known_to_both_the_login_module_and_sharepoint" + un)) and then compares the result with uh, if they are equal, the custom login module authenticates the user bypassing any further need for authentication, otherwise authentication passes to the original authentication modules as normal.
If you think there is an easier way, please let us know. We are essentially looking for the easiest/fastest way to implement this functionality that is still secure.

Hey Gary,
I'm currently using Apache running on RedHat that leverage Apache's mod_rewrite module. I've got a bank of 6 reverse proxies sitting in front of an SAP Portal and each proxy runs on a host with dual 3.33GHz processors and 8Gb or RAM. I know... they're waaay over-sized and they pretty much snooze all day.
This is the sole entry point for all SAP users and we sized them to accommodate the "worst case" of about 5000 (potential) named users, concurrently. Realistically, we've only ever had about 1500 unique users hitting the systems in a day (following an upgrade go-live, everybody is curious and wants to log on) and a typical load of about 500 to 750 users in a day.
Never had a real performance problem to speak of. As long as the proxies are tuned properly (ssl cache, sessions, etc.), you should be fine.
Setting header variables and some other "custom stuff" is handled in Perl (need Apache's mod_perl active). We've got a script that's called by all users before being passed to the Portal.
We used IISProxy.dll with an IIS web server a long time ago (5 years maybe?) but opted to can it in favor of the approach described above.
If you ask SAP, they'll recommend you use a WebDispatcher... and that's certainly an option as well.

Use of portal service in JAAS Login Module

Is it possible to use an portal service in an JAAS Login Module?
I've tried to use the IUserMappingService and always run in an Null Pointer Exception.
All needed Used DC references are set and the build and the deployment of the
login module is possible without any errors.
Best regards,
Thomas

Accessing LDAP in a custom JAAS login module

Hi,
I have developed a custom jaas login module in CE 7.1. I created a java dc which contains a class extending AbstractLoginModule. This DC is deployed on to the server using an EAR DC. I am trying to access LDAP in the custom login module. I am trying to establish an SSL connection to LDAP. For this purpose i have created a custom socket factory class which extends SSLSocketFactory. I used the code below to establish the connection.
          Hashtable<String,String> env=new Hashtable<String,String>();
          DirContext dirContext=null;
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          env.put(Context.PROVIDER_URL,ldapURL);
                env.put(Context.SECURITY_PROTOCOL,"ssl");
                env.put("java.naming.ldap.factory.socket", "com.test.ldap.MySSLSocketFactory");
                dirContext=new InitialDirContext(env);
MySSLSocketFactory is the name of custom socket factory.
During a login process, the above code results in error because the connection to LDAP server could not be established. However the same code when executed in a webdynpro DC is working without any problem. What could be the reason for this?
This is the error i could see in defaultTrace
javax.naming.CommunicationException: js24.na.domain.net:636 [Root exception is java.lang.ClassNotFoundException: com.test.ldap.MySSLSocketFactory

Hi,
I used an EJB to perform the LDAP search and called the EJB from the login module. It is working as expected.
